Pfizer Wins Celebrex Patent Challenge by Generic Manufacturer Teva
Judge John C. Lifland ruled that the patents (Nos. 5,466,823; 5,563,165; and 5,760,068) covering the active ingredient, pharmaceutical composition and method of use for Celebrex are valid, enforceable and infringed by the generic manufacturer's product. The decision, which may be appealed, prohibits Teva from launching a competitor drug in the U.S. until December 2015.
Celebrex was approved by the FDA in 1998. Its sales totaled $1.57 billion in the U.S in 2006.
